Q: The event is part of an art exhibition at the 20-21 Visual Arts Centre, which began on Saturday 18 February.
To find and keep the pieces, worth at least Â£1,000 each, people must study five paintings and solve the code within them.
One of the items was found by accident so a reward is being offered to anyone who can solve the clue linked to it.
Artist Luke Jerram said he would donate Â£500 to a charity of the finder's choice if they could solve the mystery of the "red picture".
The fourth item, the golden train, was found by a family from Grimsby in Scunthorpe's Central Park on Friday night.
Mr Jerram said he had not anticipated so many items would be discovered in the first week.
"I was expecting two or three, something like that. What I did not expect was the response of the public would be so astonishingly positive.
"I did not expect the public would go round looking in every nook and cranny of the town to try and find the artefacts."
The Visual Arts Centre said the public response had been extraordinary.
"It has created a real buzz around the place and brought in thousands of people," said the centre's visual arts officer Michelle Lally.
The final item to be found is the gold copy of a Jurassic ammonite, an ancient marine mollusc fossil.
The five objects are replicas of pieces at North Lincolnshire Museum and were made from gold worth Â£1,000, but could be worth much more.

A: Four of five gold artefacts hidden in Scunthorpe as part of a treasure hunt have been found inside a week.

Q: The 28-year-old off-spinner, who made only 22 after being promoted to open the batting on day one, claimed 3-41 as Pakistan A closed on 216-5.
Iftikhar Ahmed (92 not out) and Fawad Alam (55) added 112, while Mark Wood and James Anderson took a wicket each.
England had made 286-5 in the first of two two-day matches before the three-Test series, starting on 13 October.
"We've talked about playing aggressive cricket and attacking cricket, but in these conditions you can't blast teams out - you have to sit in and be patient," said Durham bowler Wood.
"Wickets can fall quickly and then all of a sudden you can be four down in a hurry and that changes the momentum of the game. We've just got to be patient. When we get one then that's the time to attack and try to get two or three quickly."
After a solid first day, which saw four England players pass 50, including captain Alastair Cook and Jonny Bairstow, the tourists made early inroads with the ball on a largely unresponsive pitch.
With seamers restricted to short spells by the extreme heat, Wood struck first, having Sami Aslam caught by Stuart Broad at square leg.
Moeen came to the fore with the wickets of Khurram Manzoor and Ali Asad to reduce Pakistan A to 32-3 during a pre-lunch spell of seven overs for nine runs.
It could have been even better for England had Cook held on to a two-handed catch high to his right at slip after Iftikhar edged the first ball of Stuart Broad's second spell.
The Pakistan batsman would give no further chances as he and Alam dominated the afternoon session with a stand of 112.
Their fourth-wicket defiance was finally ended by Moeen, before Anderson chipped in with the wicket of Usman Salahuddin, but by then the toil of England's efforts had begun to show.
Moeen's fellow spinner Adil Rashid, who is likely to feature heavily during the tour, was also economical and despite not taking a wicket went for just 55 runs from his 22 overs.

A: Moeen Ali impressed with the ball as England drew their opening tour game against Pakistan A in Sharjah.

Q: "How she lived is more important than how she died, and what she stood for is more important than the hatred that drove this act."
What, then, about the contrast between Jo's life, and that of her killer, Thomas Mair?
"He said I think, at the time, that he did what he did for Britain. But I think that Britain would be ashamed of him," Mr Cox said.
"I have no interest in him. I have some pity that his life was so devoid of love and so consumed with hatred that he thought this was an OK thing to do, but I have no interest in how he feels or what he thinks."
Mr Cox said he is not able to forgive the man who brutally murdered his wife.
"In order to talk about forgiveness you have to have some acceptance of how wrong and how evil what he did was, and I have seen no suggestion of any of that.
"From the way the trial was conducted, it feels like somebody who is both unbelievably cowardly and driven by hatred, but if those things were to change then it would be a different scenario.
"I think one of the reasons this happened was for a sense of notoriety and I don't want to bestow that," he added.
Although living in the aftermath of his wife's murder still feels "like a bad dream", Mr Cox said he and his two young children, aged four and five, find comfort in reminding themselves of the sort of person she was.
"Probably every other night, I ask people who knew Jo to write a story for the kids about something they did with Jo or a memory of Jo, and I'll read out one of those to the kids and they love them," he said.
"We have a lifetime of stories. Jo packed in probably 80 or 90 years into the 40 she lived.
"I'll remember her for her zest for life, an enthusiasm in almost all circumstances and about most things, an empathy towards other people and a love both of our family but also just of others."

He said: "A lot of what Jo worked on was very worthy and important but she was also very mischievous and very fun and great just to play around with and to hang around with, so we'll remember all of that as well.
"When we were on the way to the funeral and there were thousands and thousands of people lining the streets of Batley, [their son] Cuillin said 'I knew people loved mum but I didn't know this many people loved her'."
"We talk about Jo every day, we talk about the things that made her amazing and we talk about the things that made her annoying... because that also made her so human and so endearing."
It is also through Mrs Cox's work as an MP that many people will remember her.
"She was driven by a very powerful sense of empathy and so when she would meet people who had a problem, she would be committed to dealing with that problem no matter how difficult or seemingly unsolvable," her husband said.
"I used to get very frustrated because every week when she would be up in the constituency at her surgery and she would call me up and say, 'I've missed the train again', and I would be very irritated.
"But she would say, 'it was because somebody turned up and their child support allowance hadn't come through and they didn't have any money for the weekend'. She had a very personal, human connection with people."
When asked how the family are trying to move forward with their lives, Mr Cox said one of the main things they want to achieve is to continue his wife's vision through the Jo Cox Foundation, which has raised more than Â£2m to help with issues such as loneliness, Syrian refugees, autism, and encouraging women in politics.
"For us this is the beginning of something," he said, explaining that their mission is to "make sure that in the years after, what's happened to Jo awakens something which is about bringing our communities back together".
"It's what she said, we do have more in common than that which divides us.
"We are in a place in the world where that message is even more necessary and Jo, if she was alive now, would be spending the vast majority of her time on making that case and that argument.
"She's not here, so we are going to do that in her name."

A:
"Her voice has been strengthened by all this and not silenced," believes Brendan Cox, the husband of murdered MP Jo Cox.
